Title:
  subnetpool allocation not working with multiples subnets on a unique
  network

Status in neutron:
  Fix Released
Status in neutron kilo series:
  New

Bug description:
  The following scenario is not working:

  #$ neutron subnetpool-create pool --pool-prefix 10.0.0.0/8 --default-prefixlen 24
  #$ neutron net-create net
  #$ neutron subnet-create net --name subnet0 10.0.0.0/24
  #$ neutron subnet-create net --name subnet1--subnetpool pool
  >>> returns a 409

  Last command fails because neutron tries to allocate to subnet1 the
  1st unallocated cidr from 10.0.0.0/8 pool => 10.0.0.0/24 but subnet
  net as already 10.0.0.0/24 as cidr (subnet0) and overlapping cidrs are
  disallowed on the same network!
